There was 17 mins between tweets
Then 7 mins
Now 14 mins
Q said 7 delta today
And also +7
So starting with the 7 min delta
+7 suggests the next delta would be 14
And sure enough, after 14 mins, there is another tweet
Looking for the next after 21 minsโฆ
But now, by Twitter's calculation
22 minutes has passed
So if the delta calcs were right
It was only about the few tweets already received
